Minimize wheel-hop and reduce rear cradle movement in your 2012 and newer Camaro with a Rear Cradle Insert Bushing Kit from BMR Suspension. Manufactured from low-deflection polyurethane to allow better handling without significantly increasing noise, vibration, or harmonics. The BMR Rear Cradle Insert Bushings (BK040) install inside the air gaps of the stock rubber bushings. This product is recommended for customers who plan on racing their Camaro at the track occasionally, but plan on street-driving it most of the time. The rear cradle does not need to be removed during installation of the bushing inserts. Installation time is 3-4 hours.

How are these compared to just replacing the bushings? Do they work the same as polyurethane bushings? Just easier to install? I'm debating what direction to go...I was thinking polyurethane sub frame bushings/diff bushings and the hotchkis chassis brace..but if these inserts will do the same thing then I will go this route

These rear cradle inserts don't control the rear cradle movement nearly as well as the full rear cradle bushings but for some people they do the job it just really depends on what you are doing with the vehicle. These rear cradle inserts work with the factory rear cradle bushings by taking up the voids which helps stiffen up the bushings. The full rear cradle bushings replace the entire factory rear cradle bushings. The rear cradle inserts are definitely much easier to install than the full rear cradle bushings. I personally like the full rear cradle bushings much better than the rear cradle inserts and if you are planning on making more than 450hp I would definitely recommend going that direction. Out of the three things you have listed you will get the most benefit from the rear cradle bushings for sure.
